Hepatocellular carcinoma(HCC) is one of the most common cancers worldwide and has a poor prognosis if untreated. It is ranked the third among the causes of cancer-related death. There are multiple etiologic factors that can lead to HCC. Screening for early HCC is challenging due to the lack of well specific biomarkers. However,early diagnosis through successful screening is very important to provide cure rate. Liver transplantation(LT) did not gain wide acceptance until the mid-1980 s,after the effective immunosuppression withcyclosporine became available. Orthotopic LT is the best therapeutic option for early,unresectable HCC. It is limited by both,graft shortage and the need for appropriate patient selection. It provides both,the removal of tumor and the remaining cirrhotic liver. In Milan,a prospective cohort study defined restrictive selection criteria known as Milan criteria(MC) that led to superior survival for transplant patients in comparison with any other previous experience with transplantation or other options for HCC. When transplantation occurs within the established MC,the outcomes are similar to those for nonmalignant liver disease after transplantation. The shortage of organs from deceased donors has led to the problems of long waiting times and dropouts. This has led to the adoption of extended criteria by many centers. Several measures have been taken to solve these problems including prioritization of patients with HCC,use of pretransplant adjuvant treatment,and living donor LT.
